At the blog “sunshine hours” it seems the Antarctic has set a new record. He writes:

As you may know, I have been using Cryosphere’s Antarctic Sea Ice Area data to show the record levels of Antarctic Sea Ice.

But I just found another data set, NOAA’s Sea Ice Extent here. (thanks to commenter HaroldW at the Blackboard)

And it turns out day 265 set an all time record, and then day 266 (Sept 22nd) broke that record. Days 265 through 270 are now the 6 highest Antarctic Sea Ice Extent’s of all time (in the satellite record)!
